A conroaArIoN v A ferie rimane APPARATUS Application rfiled December 14, 1929. Serial No. 414,078.

M invention relates to apparatus for filling ags with measured quantities of material, particularly with material having a tendency to adhere' to and clog the apparatus,

@such as salted peanuts,'and has for its 'object the provision of apparatus of the character designated which shall include simple eRective means for filling/the bags and for preventing adherence offsaid material. f

i@ A further ob'ect of my invention is to provider a bag filling apparatus embodying ya moving, measuring and dispensing element,

together with means for heating the element and the material to prevent'adherence of ma.-

1,5J terial to the parts of the apparatus.

A still further object of my vinvention is to provide a bag filling apparatus having a moving, measuring and dispensing element therein, together with means for preventing 2o adherence of the material to the apparatus including an air blast which opens the bags and delivers the material thereinto.

' In apparatusfor bagging certain mate-'lw rials`, particularly materials which have been 2B given a coating of salt, such as salted peanuts,

difficulties have been encountered due to particles adhering to the moving parts thereof and interfering with its proper operation. I n order to preventthis objectionable adherence of the material it has heretofore been the practice to providel the moving parts with some sortv of scra er or brush. While this expedient served or the' parts which4 could be reached with the scraper, it could not be arranged so as to reach into-the measuring cups of the apparatus. I I have found where materials have-salt adhering thereto, such as saltedpeanuts, are being bagged, that if an air blast be arranged to act directly upon the peanuts entering the empty bags and, preferably, if the moving element for measuring and dispensing the peanuts be heated, the material does not adhere thereto and Scrapers and thelike may be dispensed with. In accordance with my invention, I provide a discharge chute with an air pressure nozzle incorporated in the chut-e for directin -an air blast downwardly into the ba s to e' filled toopen the bags and to 50 expel t e material into the bags thereby keeping the chute clean. In addition, I provide a anged wheel having a series of measuring oups provided in the flange. Telescoping over the flanged wheel is a stationary cylindrical member having spacedopeningstherein permitting the reception'of the material into the cups and the vdischarge of the material therefrom. Disposed within the cylindrical member is van electrical heatingelement by means of which the necessary degree of heat may be supplied to the cylind'ricallmember to prevent adherence of the material. Y

Apparatus embodying features of my invention is illustrated inthe accompanying drawings, forming a part of this application, wherein Fig. 1 is a side View, partly in section, of. my improved apparatus;

Fig. 2 is an end vielw thereof; and

lBig. 3 is a transverse'sectional view of the measuring and dispensing' wheel together with the heating means.

Referring to the drawings, I show a hopper 10 having-an opening 11 at the bottom thereof and leading to a dlscharge spout 12.*'

At 13 is shown a measuring and dispensing wheel having a flange 14 provided with a series of dispensing cups 16 therein. The wheel 13 is mounted upon a shaft 17 driven from a motor 18 through a reduction gear.

bon 19. Adjacent the wheel 13 is astationary cyllndrical member 21 supported by 'a' frame element 22 and in telescoping relation with thewheel 13. The member 21 has a solid disk Wall 23 and the wheel 13 is in the form ofv a disk so as torovide between the two disks an enclosed c amber. y

The cylindrical member 21 is provided with an upper opening 26 in communication with the discharge spout 12 of the hopper 10 and With a lower opening 27 which communicates with a discharge chute 28 leadirg to the point of delivery of the material being bagged. It will be obvious that, as thelwheel 13 is rotated, the cups 16 are filled with the material through the opening 26 and, upon further rotation, when opposite the opening 27, discharge the measured Aquantities of the material into the chute 28.

-In order to preventmaterial adhering to i trical heatin 4the cup 16 and wheel `13, I rovide an elecelement 31 wit the chamber dened by t e Wall 1,3 and the cylindrical member 21, said heating element embodying the usual resistance 32. The heating element. 31 is supplied with current from a circuit.

33 which-is provided with a rheostat 34 for varying the current flow thereto and thus the radiation of heat therefrom. In

varyino' b I am enabled to provide` just the this manner l degree of heat requiredto prevent sticking ofthe material and no more.

The discharge chute 28 terminatesnn a nozzle 36 which is arranged above a moving belt 37 having cups 38 mounted thereon whichreceive filled bags and convey them to a point of packaging, not shown. \Extend ^1belt 43.

` 'nozzle' 36 35 are'held beneath the end -of the nozzle-3 6 y ofthe pockets 35 .being driven i for bagging material which is simp .40 which embodies' ,f tions. without departing from the. spirit 'l thereof andIdesire therefore that only such limitations shall be vplaced thereupon l -Y 5o ifically 4 'A' serves to keep it c setiorth in the appended claims.

`a series of) cup ceiving and 'tional-yq c flanged W to 'pigrmit `material to pass into the cups and Yto f discharged' therefrom, and an electric, resistance element carried by the stationary `V -j vcylindrical and di c lindrical member. andt e t e wheel and preventadherence of material ing downwardly nozzle 41 throiigh which is continuously supplied Ean air blast' from-a fan 42 which is driven directly by the motor -18 through a The air blast through the nozzle 41 acts directly on the nutsin the chute 28, lear and also serves to open the bags 35 when :for lling, Inpractice, the bags in a flattened condition, whereupon the air 0. blast inilates them and opens them wide or the material to fall thereinto when one of the pockets 16V comes opposite the opening' 27.

When'illed the bags are dropped into one 38 in the belt 37, the belt 37 of a belt 44.

From the foregoing it will be apparent I that-I have devised an improved a paratus e of design and operation and ,material in the into Athe chute 28 is an air.
